CAPE CANAVERAL, Fla. - In Orbiter Processing Facility 3 at NASA's Kennedy Space Center in Florida, members of space shuttle Discovery's STS-131 crew participate in training activities during the Crew Equipment Interface Test, or CEIT, for their mission. Here, Mission Specialist Clay Anderson is given the opportunity to operate one of the cameras that will be used to photograph the reinforced carbon carbon panels during his mission. The panels are part of the shuttle's thermal protection system. The CEIT provides the crew with hands-on training and observation of shuttle and flight hardware. The seven-member crew will deliver the multi-purpose logistics module Leonardo, filled with resupply stowage platforms and racks to be transferred to locations around the International Space Station. Three spacewalks will include work to attach a spare ammonia tank assembly to the station's exterior and return a European experiment from outside the station's Columbus module. Discovery's launch is targeted for March 18. For information on the STS-131 mission and crew, visit http://www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts131/index.html.

7 x 10-Foot Atmospheric Wind Tunnel (AWT)

description

Summary

Force Test set-up in 7 x 10-Foot Atmospheric Wind Tunnel (AWT). In 1928, the NACA decided to replace its original Atmospheric Wind Tunnel (AWT #1) with two tunnels--the 5-foot vertical tunnel and a 7 by 10 foot rectangular throat tunnel. Both were open-throat, closed-return-passage tunnels and were housed in the same building the first wind tunnel had been located in. While the 5-foot vertical tunnel was to be used mainly for spin tests, the 7x10 was an all-purpose tunnel although the main intent was to study stability and control problems. Construction was completed in the summer of 1930; calibration later that same year. The balance was installed and the tunnel went into operation in early 1931. There was a 6-component balance in this wind tunnel. The balance could support either static or rotation tests.
